I have no idea what phono cartridges can be used with this arm. Plus, as has been stated previoiusly, there is an effective mass problem that must be taken care of with a lighter tone arm head.
I have several Jelco SA-370 arms, as they were standard fitment on London Acoustical Developments' semi professional turntables from about 20 years ago, and I have rather more of these than is good for me. I also have the very SA-750D reviewed by Hi-Fi World, as I reviewed it and liked it so much I bought it!
The SA-370 is basically an older version of the SA-750D and the 750 brings the design up to date with better bearings, better wiring and a nicer finish. Comparing the two, I would say the SA-750D definitely has a notable advantage over a standard SA-370 as it has a more focused soundstage, better dynamics and a 'cleaner' top end. That said, I do have an SA-370 that has been rebuilt and re-wired by Johnnie at Audio Origami - this improves on the standard SA-370 considerably but I have yet to do a direct comparison with the SA-750D!
Cartridge-wise I generally usa a Goldring 2500 in the SA-750D and have also had excellent results from an Audio Technica AT-OC9MLII MC. A whole range of things move around the several SA-370s I have, including an Audio Technica AT110E (good), an Ortofon 2M Red (also good) an AT-440MLa (bad) and a Grado Black (fitted it a couple of weeks ago and haven't listened yet).
